I'm having problems uploading/replacing a pre-post.
The first time I uploaded my image for today's contest, everything was fine.
However, this morning, I spent some more time on it, wanted to replace the original, and no matter how many times I try, the original post won't update.

What I did next, was to upload the original source. That worked. However, when I wanted to upload my edited entry again, it took the very first image I posted yesterday.
I really don't get it.

Anyone else experiencing something similar?

press F5 forcing the page refresh

I pressed it 500 times by now
It's not in the refresh.. Checked it on laptop, same problem.
It's not in the cache, checked it on I-pad, still the first image shows, not the updated one.

Pfew, I finaly found what the problem was.
The uploaded image exceeded the 525 kb-limit.
The image was 523 kbs, which is about 538.000 bytes.. Which is too big. Pfff!
Normally when you upload your image the first time, and it exceeds the size, you get a warning... Apparantly when you have already uploaded an image and want to replace it, it doesn't give a warning. It says 'uploaded succesfully', but nothing was done instead.

Anyway.. Solved!
